When using a surge pipe in a vessel, influences from vessel installa-
tions and turbulences can be excluded. Under these prerequisites,
the measurement of products with low dielectric values (ε
r
value
≥ 1.6) is possible. In very adhesive products, measurement in a surge
pipe is not recommended.

Instructions for orientation:
•
Note marking of the polarisation plane on the sensor
•
With threaded fitting, the marking is on the hexagon, with flange
connection between the two flange holes
•
All holes in the surge pipe must be in one plane with this marking
Instructions for the measurement:
•
The 100 % point must be below the upper vent hole and the
antenna edge
•
The 0 % point is the end of the surge pipe
